Need tips to leave bronze...

So yea guys, i started from Bronze 5 now i'm here in bronze 1 ... And its really hard to leave this one . I play main support, already went to promo like... 3 times, lost them all . Today i went from 86 lp to 11... Now i had to dodge because i had french players on my team, and it's better loosing 3 lp than 18. Take a look at my builds, and tell me if anything is wrong, and if yes what to change ? Also yes, i place wards, all the mother efing time , don't flame ,use quick cast... But what else do i have to change to finally get silver ? Help me out ..
